The Symetrix SymNet ARC-PS is a dedicated, rack-mountable power supply unit designed to provide reliable and stable power to Symetrix ARC (Architectural Remote Control) wall panels and keypads within a SymNet digital signal processing system. This unit serves as the central power hub for these remote control interfaces, ensuring they operate consistently without drawing power from the main SymNet DSP hardware. By centralizing power distribution, the ARC-PS simplifies system wiring, enhances reliability, and provides a clean, isolated power source that minimizes the potential for ground loops or noise interference that could affect control signals. It is an essential component in medium to large installations where multiple ARC panels are deployed across a building, such as in corporate facilities, schools, houses of worship, and performance venues.

The power supply is engineered for continuous, 24/7 operation, featuring robust overcurrent and overvoltage protection to safeguard connected ARC devices. It typically provides multiple output channels, each capable of powering several ARC panels via standard low-voltage cabling (often CAT5e or similar). This daisy-chain capability reduces the number of home-run cables back to the equipment rack, streamlining installation. The unit is designed to integrate neatly into a standard 19-inch rack, usually occupying 1U of space, and includes status indicators for power and output channel activity, allowing for quick visual verification of operation.

As a system component, the SymNet ARC-PS works transparently behind the scenes, enabling the ARC wall panels to provide intuitive user control over audio zones, source selection, volume, and preset recall within a SymNet-managed audio system. Its dedicated design ensures that the control network remains stable and responsive, which is critical for user satisfaction and system uptime. By providing a centralized, robust power solution for the control layer, this power supply plays a foundational role in creating a professional, scalable, and user-friendly installed audio environment.
